PSU tests OK but when changing to another one, PC boots
My PC stopped working the other day. Couldn't turn it on anymore. There was a green light that turned on, on the motherboard, other then that, nothing. No fans, no beeps, nothing on the display. Tested the PSU with a PSU tester, it tested OK. Every voltage and measurement within its range. Still when changing to a different PSU, everything boots and starts as normal. Any known possible explanations to this?
